That is odd. That is a whisper over 5,000 RPM for both 36V and 42V.
I would have guessed 42V would have spun the motor a bit faster than 36V.

The only reason that comes to mind is because it ran out of Amps and I don't think that would be the case with a 400A controller and 7 new CR-200 batteries.

I guess I'll have to do some experimenting with 6 and 7 batteries on 18.3" tires before I sell my 36V chargers.


@ Jack12002 -- Speed at 5,018 RPM:
18" Tires = 20.6 MPH
20" Tires = 24.0 MPH
22" Tires = 26.4 MPH
